Application :filed February 1, 1917. Serial No. 145,882.

To @ZZ whom t may concern.

Be it known that I, EDWARD J. BARRETT, a citizen of the United States,and residing at New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Lock Devicesfor Shade-Rollers, of which the follow in is a specification, such aswill enable those skilled in the art to which it apper tains to make anduse the same.

This invention relates to means for supporting shade rollers in positionand for locking them against displacement, and the object thereof is toprovide a combination device of this class which is simple inconstruction and eflicient in use, and which will prevent the accidentalunwinding of the tension springs of rollers of the class specified,occasioned by the disengagement thereof from the supports as usuallyconstructed.

The invention is fully disclosed in the following specification, ofwhich the accom panying drawing forms a part, in which the separateparts of my improvement are designated by suitable reference charactersin each of the views, and in which Figure l is an inside view of the topportion of a window frame andl indicating the use of my improvement;

Fig. 2 a face view of the combination support and lock device shown inFig. 1 on an enlarged scale and indicating the angular shank at one endof the shade roller in section;

Fig. 3 a section on the line 3-3 of Fig. 2;

Fig. a a section on the line 4.-4 of Fig. 3;

Fig. 5 a face view of the base plate of my improved support and lockdevice with a lock spring secured thereto;

Fig. 6 an inside face view of the casing of the device; and, i

Fig. 7 a face view of a lock plate which I employ.

ln Fig. l of the drawing, I have indicated at a the top portion of awindow frame and at Z the top sash of the window, and supported in theside portions a2 of the frame is the usual shade roller c, the shank atone end thereof being mounted in the usual keeper 02, while the angularshank o3 thereof is mounted in or supported by my improved support andlock device eZ. l

rlhe support and lock device as shown Y consists of a base plate CZ2, acasing Z3 and a lock plate (Z4, as shown in Figs. 5, 6 and 7 0f thedrawing.

Secured to the base plate Z2 by means of screws Z5 is a flat sheet metalspring` c, the top of which is provided with flaps e2 bent at rightangles thereto, and the central portion thereof with an aperture es. Theplate [Z2 is also provided with a plurality of aper- 'tures Z6 throughwhich are passed screws,

nails, or the like for securing the device to the window frame, or oneof the side members a2 thereof.

The casing Z3 is channel-shaped in form in cross section, or consists ofa front plate ZT having side and bottom lianges Z8 bent at right anglesthereto, and which are adapted to bear on the base plate UZZ. The casing@Z3 is secured to the base plate by a screw f passed through an apertureZ9 in said casing and into an aperture cZlO in the base plate (Z2, andthe side flanges (ZS of the casing CZS, when said casing is secured tothe base plate cZ2, pass outwardly of the flaps e2 in the top portion ofthe spring e, and said flaps serve to hold the top portion of the casingZ3 against movement as will be readily understood.

The bottom portion of the casing Z3 is provided with an aperture CZ inwhich is mounted a push button g, the inner end of which is providedwith an enlarged head g2 adapted to bear on the bottom portion of thespring e, as clearly shown in Figs. 3 and 4. The top portion of thecasing Z3 is cut out centrally thereof to form an oblong aperture Z12through which, in practice, the angular shank c3 of the shade roller cis adapted to pass.

The lock plate Z4 is provided in the top portion thereof with an angularaperture ZL through which, or in connection with which the angular shankc3 of the shade roller o is adapted to operate, as indicated in Fig. 3of the drawing, and the lower end portion of the lock plate Z4 isprovided with a backwardly directed stud h2 which is adapted to operatein connection with the aperture e3 in the lock plate e, as shown in saidgure.

In the use of this device, the base plate (Z2 is first secured to oneside member of the frame of a window, after which the casing cl3 issecured to said base plate, the push button gbeing inserted in place inthis last operation, after which the shade roller c is connected withthe usual keeper c2. The lock plate ZL is then connected with theangular shank c3 of said roller, and said plate is then forceddownwardly into the lock device through the top thereof, the shank c3 ofthe roller passing through the aper ture i12 in the casing cl" in thisoperation, and the downward movement of the lock plate ZL over thespring c moves said spring inwardly until the stud 7b2 on the plate d4*comes in line with the aperture c3 in said spring at which time saidspring moves outwardly into the position shown in Fig, in which positionthe plate Z4 is held against movement, which in turn locks the shank c3of the roller c against displacement.

lVhen it is desired to detach the shade roller c from the window framefor cleaning the same, or substituting another therefor, all thatisnecessary to accomplish this result is to force the push button,(/einwardly to detach the spring c from the lock plate el* whichpermits the withdrawal of said plate and the shank portion G3 of theroller from the lock device as will be readily understood.

My yinvention is not limited to the details of construction herein shownand described, and changes therein and modifications thereof may bemade, within the scope of the appended claims, without departing fromthe spirit of my invention or sacrificing its advantages.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. A support and lock device yfor the angular shank of shade rollers,comprising. a spring, a casing inclosing said spring, a lock plateadapted to be connected withsai d angular shank and to be passeddownwardly through said casing and engage said spring to lock the sameand said shade roller against displacement, and meansV for -opn eratingsaid spring to release `said plate.

A lock device for the shank of shade rollers comprising a casing, aspring mount edinsaid casing, anda lock memberdetachably connected withthe shank of. a

roller and adapted to operate in connection with said spring wherebysaid roller may be supported and held against displacement and a pushbutton device mounted in said casing and adapted to release said springfrom said lock member.

3.` A support and lock device for the Shanks of shade rollers, a casing,a spring mounted in said casing, said spring being provided with anaperture, a lock member provided with an aperture and a projectingmember, said lock member being adapted to be yconnected withthe shanksof shade (rollers by passing said shanks through the aperture therein,the projection on said lock member' `being adapted to operate inconnectionwith the aperture in said spring to lock the roller ora shankthereof in said casing, and means in'said casing for releasing-saidspring from said lock member.

l.n In a device of the 'class described, a casing composed-of separateparts, vthe top portion of said casing being open and the frontwallthereof being provided with an upwardly directed aperture, a springmounted in said casing and provided centrally thereof with an aperture,a push buttondevice mounted in the bottom portion of said casing andnormally extended by said spring, and a lock member adapted to be passedA downwardly through said 4casing and adapted to operate in connectionwith Ithe aperture lin said lspring whereby said member is lockedagainst displacement, said member being adapted to support the shank ofa shade roller, said lock member 'being adapted to be'released from saidspringv by means of said push button device.

In testimony that l claim the foregoing as my invention I have signed myname in presence-.of the subscribing witnesses this 31st day ofJanuary'19l7.
